Elias observed a sample in the classroom. the sample was a liquid at room temperature. he performed a conductivity test and found that it did not conduct electricity. which classification would best fit the sample?
a) ionic
b) metal
c) nonmetal
d) salt

C.  nonmetal.

Explanation:

It is not ionic because it did not conduct electricity.

There is only one liquid metal  at room temperature and that is mercury, which will conduct electricity.

A salt is usually solid at room temperature and if it is in solution will conduct electricity.

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
